Statspack ORA-00001 unique constraint violated错误的解决

我这里分两部分，这个问题在网上查到一个解决方案，从mos里又看到更加全的。

============================转载部分===========================================

ORA-00001: unique constraint (PERFSTAT.STATS$SQL_SUMMARY_PK) violated

ORA-06512: at "PERFSTAT.STATSPACK", line 1361
ORA-06512: at "PERFSTAT.STATSPACK", line 2471
ORA-06512: at "PERFSTAT.STATSPACK", line 91
ORA-06512: at line 1

这个错误此前从未遇到，但是既然是主键冲突，那肯定是存在重复主键的数据。

肯定能暂时解决问题方法就是暂时禁用唯一约束检查:
ALTER TABLE PERFSTAT.STATS$SQL_SUMMARY 
MODIFY CONSTRAINT STATS$SQL_SUMMARY_PK DISABLE NOVALIDATE;

然后观察数据来发现根本问题，最后彻底解决之。

到Metalink搜索了一下，发现存在一个相关Bug，Bug号为:2784796.
在设置了cursor_sharing为similar或者force之后，可能触发此Bug，导致主键冲突。

此bug据说在Oracle10g中已经修正。

execute statspack.snap

或
BEGIN statspack.snap; END;

执行创建snap的时候报错

ERRORat line 1:
ORA-00001 : unique constraint (PERFSTAT.STATS$SQL_SUMMARY_PK) violated
ORA-06512 : at "PERFSTAT.STATSPACK",line 1361
ORA-06512 : at "PERFSTAT.STATSPACK", line 2442
ORA-06512 : at "PERFSTAT.STATSPACK", line 91
ORA-06512 : at line 1

从MOS上看，这个bug在9.0.1.4 到 9.2的一个bug

解决方法如下：

sqlplus " / as sysdba" 
SQL> spool run_statspack.txt 
SQL> create or replace view STATS$V_$SQLXS as
